KELCO E30 - Low Voltage AC Supply with Remote Input Wiring

Alarm Relay (Relay 2) in Detail
After selecting an operating mode and pressing “P” the menu asks you if you want
to use the alarm relay. The E30 contains a dedicated relay (Relay 2) with 16 Amp
240VAC rated normally open voltage free contacts that can be used to control an
external alarm, an auto dialer or even a second pump. Assuming you have
selected either mode 1 or mode 2 you will be asked if you want to use the alarm
relay. Selecting YES and pressing the “P” button takes you to the rst of 7 screens
that allow you to select how you would like the alarm relay to behave.
Pressing the up or down buttons steps you through the available congurations.
Once you have made your choice simply press the “P” button to lock your selection
in and to move to the next menu question. Note that you are not asked if you want
to use the alarm relay if you have selected mode 3, snap switch. This is because
the snap switch mode uses its own unique setting for the alarm relay.
The seven possible alarm relay congurations are : -
Closed if any Fault Develops
In Mode 1 with this option selected the E30 will close its alarm relays contacts if
the pump runs dry or if any of the advanced functions are active and detect a
problem. For example if the anti cycling set point is exceeded. In Mode 2,
Pressure Guard, the alarm relay will close on a high or low pressure fault.
Closed if Pump is Off
If this conguration is selected the alarm relay’s contacts will be closed
whenever the pump is off and they will be open whenever the pump is running.
Closed if Pump is On
If this congurations is selected the alarm relay will mimic the main pump relay
and be closed whenever the pump is running and open wherever the pump is
off.
Closed only on a High Pressure Fault
This conguration relates to Mode 2, Pressure Guard. It will provide a set of
closed contacts if the pressure guard detects too high pressure. At all other
times the relay 2 contacts will be open.
